River corridors are home to nearly 3 billion people, and support agriculture, commerce, diverse ecosystems, and hydropower generation. River mobility describes the processes by which alluvial river morphologies change through time—from steady deposition of sandbars to the wholesale diversion of a river course across a landscape. River movement can ...
Rivers are dynamic features of Earth’s surface that contain information about both past and present landscape processes. Shifts in the balances of sediment and flow in a watershed are often reflected in the character of the riverbed, channel geometry, or patterns of sediment transport, making rivers an invaluable tool for investigating changes in t...
High-resolution 3D seismic data analysis was integrated with a calibrated well and biostratigraphy data to present the first overview of a buried Pleistocene canyon system on the upper slope of the eastern Niger Delta, the Galabor Canyon. Attribute maps of specific horizons allow documenting the changing morphologies and infill lithologies of two m...
Deciphering the impact of short-term or long-term forcing on fluvial incision, as well as understanding the influence of local (channel lithology and morphology) and global (tectonic motions) parameters in the spatial variation of incision efficiency, are ongoing geomorphological research fields. To shed new light on these issues, we chose to study...
The Kurtzhals property is in Section 19, Township 30N, Range 3 in Cedar County, Nebraska. The present land use is agricultural row crop, but past use included hog production. Two active irrigation wells are located on adjacent properties to the west and southwest. An irrigation well was installed in the northwest corner of the property in 2022. Due...
Spatio-temporal patterns of glacial retreat determine the intensity of geomorphological, hydrological, and ecological processes in the ice-free areas of the Antarctic Peninsula region. The chronology of glacial oscillations in the region following the Last Glacial Maximum (LGM) is still poorly constrained and mostly limited to data from a few sites...
